Tu Head Differences

[tomcolinjones 26]

hello!

I was wondering if someone could help me with this small question. Are the 205 fitted tu engine cylinder heads the same? I.e valve sizes, cam profile, port spacings, bolt pattern.

reason I am asking is that I have just bought a tu9 engined 205. And due to the rarety of tu3s engines complete, could I fit my tu9 head to the tu3s block? I'm.hoping that the heads are identical.

thanks in advance, Tom.

The heads aren't identical no but the tu9 head will physically fit

 

The valves and ports in the 3s are bigger and the cam more sporty

I have a tu3s head I could be persuaded to part with
